Raspberry plant named ‘DrisRaspNine’

ABSTRACT

A new and distinct variety of raspberry plant named ‘DrisRaspNine’ particularly distinguished by having a self-fruitful plant that bears medium-sized, strongly red berries, is disclosed.

Genus and species: Rubus idaeus L.

Variety denomination: ‘DrisRaspNine’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct raspberry variety designated ‘DrisRaspNine’ and botanically known as Rubus idaeus L. This new raspberry variety was discovered in Ventura County, Calif. in February 2011 and originated from a cross between the proprietary female parent raspberry plant ‘RB629.4’ (unpatented) and the proprietary male parent raspberry plant ‘RB629.5’ (unpatented). The original seedling of the new variety was first asexually propagated at a nursery in Santa Cruz County, Calif. in 2011. ‘DrisRaspNine’ was subsequently asexually propagated and underwent further testing at a nursery in Ventura County, Calif. for five years. The present invention has been found to be stable and reproduce true to type through successive asexual propagations via tissue culture and root cuttings.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Ventura, Calif.:

-   -   1. Self-fruitful plant; and     -   2. Medium-sized, strongly red berries.

DESCRIPTION OF THE PHOTOGRAPHS

This new raspberry plant is illustrated by the accompanying photographs which show fruit, flowers and leaves of the new plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are six months old.

FIG. 1 shows close-up views of typical flowers and fruit at various stages of development.

FIG. 2 shows a close-up view of fruit.

FIG. 3 shows both the upper surface and the lower surface of the plant leaves.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisRaspNine’. The data which define these characteristics is based on observations taken in Ventura County, Calif. from 2011 to 2015. This description is in accordance with UPOV terminology. Color designations, color descriptions, and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘DrisRaspNine’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisRaspNine’ was taken from six-month-old plants. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2^(nd) edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘DrisRaspNine’ differs from the proprietary female parent ‘RB629.4’ (unpatented) in that ‘DrisRaspNine’ has a higher percentage of marketable fruit and the fruit has better flavor than the fruit of ‘RB629.4’. Additionally, plants of ‘DrisRaspNine’ have a more vigorous growth habit and better emergence of canes after planting than ‘RB629.4’.

‘DrisRaspNine’ differs from the proprietary male parent ‘RB629.5’ (unpatented) in that ‘DrisRaspNine’ has brighter colored, firmer fruit than ‘RB629.5’.

‘DrisRaspNine’ differs from the commercial variety ‘Driscoll Maravilla’ (U.S. Plant Pat. No. 14,804), in that ‘DrisRaspNine’ has medium sized, soft fruit having an easy adherence to the plug, whereas ‘Driscoll Maravilla’ has large sized, firm fruit having a medium adherence to the plug. Additionally, ‘DrisRaspNine’ usually has three lateral leaflets with a free arrangement, whereas ‘Driscoll Maravilla’ usually has five lateral leaflets with an overlapping arrangement.

‘DrisRaspNine’ differs from the commercial variety ‘DrisRaspSeven’ (U.S. Plant Pat. No. 25,045) in that ‘DrisRaspNine’ has medium sized, soft fruit with an ovate shape, whereas ‘DrisRaspSeven’ has large sized, medium firm fruit with a long conical shape. Additionally, ‘DrisRaspNine’ usually has three lateral leaflets and terminal leaflets that are convex in cross section, whereas ‘DrisRaspSeven’ usually has five lateral leaflets and terminal leaflets that are flat in cross section. 

We claim:
 1. A new and distinct variety of raspberry plant named ‘DrisRaspNine’, substantially as illustrated and described herein.
